Corneal Ring Inserts Can Relieve Symptoms of Keratoconus
Keratoconus is a condition of the eye in which the tissue of the cornea becomes thin and begins to protrude outward. The word keratoconus means cone-shaped cornea, and this condition can cause visual distortion and deterioration. Prescription glasses or lenses can address symptoms such as blurred vision or decreased night vision in the early stages. As the condition advances, more aggressive treatment becomes necessary. Our doctors can provide patients with corneal ring inserts at our Toronto-area ophthalmology offices to correct the distorted shape of the cornea and improve vision. We are experienced in treating all stages of the condition, and consistently achieve excellent results for our patients. If you suffer with keratoconus and would like to learn more about your treatment options, please contact our office to make an appointment with one of our vision specialists.
The exact cause of keratoconus is unknown, but experts believe the change in the shape of the cornea may occur as a result of:
- Excessive rubbing of the eyes
- Conditions like vernal keratoconjunctivitis and retinopathy
- Prolonged use of contact lenses
- Enzyme abnormalities
A Minimally Invasive Procedure
Ophthalmologists place corneal ring inserts within the cornea to provide the gentle pressure necessary to correct the irregular shape of the cornea. This treatment can improve vision without damaging or changing the structure of the eye. Corneal ring inserts are a much less invasive alternative to corneal transplants, which used to be the only option to restore vision once keratoconus became advanced.
During the procedure, your surgeon uses a laser to create a small incision in the surface of the cornea. Your surgeon will insert the ring through the incision. It can immediately improve vision by flattening the cornea. The entire procedure usually takes less than 15 minutes, and the inserts themselves are replaceable if your vision changes after your procedure. Most patients are back to their daily routines after just a couple of days of rest, and our skilled surgeons used advanced techniques and tools to minimize risks.
Biocompatible Materials for Excellent Results
The corneal ring inserts are made from acrylic plastic, just like many varieties of intraocular lenses (IOLs). Unlike IOLs, corneal ring inserts do not replace any part of the natural eye structure, but instead provide the pressure needed to slightly flatten the cornea, restoring a normal dome-like curvature for improved vision.
Advantages of Corneal Ring Inserts
Corneal ring inserts have been shown to vastly improve patients' vision immediately. Undergoing this minimally invasive procedure can delay or eliminate the need for a corneal transplant, preserving the natural structures of the eye. We will conduct a thorough preliminary consultation to determine if ring implants are the best solution for your needs. We also perform corneal cross-linking, a keratoconus treatment in which ultraviolet light is used to strengthen collagen cross links, restoring a normal shape to the cornea.
